Rated AEC-Q100, this part is qualified for automotive applications where reliability screening and temperature cycling are required — suitable for cabin or chassis-domain ECUs that demand a hardened clock source. The MEMS resonator replaces a quartz crystal, offering improved shock and vibration tolerance and faster startup compared to a traditional crystal oscillator — a practical advantage in automotive and industrial environments. ## Supply voltage and output drive Operates from a 2.25V to 3.6V supply, covering 2.5V and 3.3V rails without an external regulator — the wide input range simplifies power tree design. CMOS output drives standard logic families directly; maximum supply current is 35 mA when enabled and 22 mA when disabled via the Enable/Disable function. Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a standard footprint for 7x5 mm oscillators, compatible with reflow soldering profiles. Surface-mount package supplied on Tape & Reel, suitable for automated pick-and-place assembly. The part is available for new designs and volume production. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1121AE2-125.0000T MEMS Oscillator 125 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1121AE2-125.0000T XO (Standard) MEMS oscillator, 125 MHz CMOS output, ±25 ppm stability, AEC-Q100 qualified, 2.25V-3.6V supply, -20°C to 70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1121","Package":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"125 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1121","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DSC1121AE2-125.0000T AEC-Q100 qualified?","answer":"Yes, the DSC1121AE2-125.0000T carries AEC-Q100 qualification, making it suitable for automotive-grade applications that require reliability stress testing and temperature cycling per the standard."},{"question":"Can DSC1121AE2-125.0000T replace a standard 125 MHz crystal oscillator?","answer":"Yes, it is a drop-in replacement for a 125 MHz crystal oscillator in CMOS logic systems.
